Brace yourself. Those cute little dragons are hitting puberty.

Game of Thrones: Ascent, the hit social game based on the hit TV show, gets a major expansion today that adds new content to the Facebook, iOS, and Android versions, a lot of it based on the fifth season of the show that started on April 12. The free-to-play title originally came out in 2013 and has had more than 10 million players, according to developer Disruptor Beam. It also saw a 30 percent boost with the launch of the show’s fifth season. It’s a healthy hit in a mobile market that could reach $30 billion, with revenues expected to exceed the console industry’s this year, according to market researcher Newzoo.

Titled Fire & Blood, the update includes a new mode, Tales of Fire and Ice, which enables you to send your Sworn Swords on missions and earn rewards. You’ll also be able to grow your baby dragons into adolescents.

This is Game of Thrones: Ascent’s second expansion. The first, The Long Night, came out back in October 2014.
